With the upgrade to Supporter you have space for more than 20000 photos ( the free account has space for 420 photos).
Moreover, the latest photos posted by a supporter member appears in a dedicate box in the Galleries page (in the desktop version) or in the "Forum and Galleries" column of the home page (in the smartphone version).
In future, the supporter account will cost 25 euro per year: at the price of a dinner at restaurant or a T-shirt, you can get almost unlimited space for your photos!
Currently the supporter membership is FREE for members of the international version that have published at least 200 photos!
If you already have 200 or more photos, send a mail to firstname.lastname@example.org to get your free supporter account!
